A Three-Component Model Based on Macropropagation Phenomena Approach for Complex Building Scattering

Mehdi Ait-Ighil, Fernando Perez-Fontan, Joel Lemorton, Frederic Lacoste, Christophe Bourga, Michel Bousquet
2015 International Journal of Antennas and Propagation  
This model is based on asymptotic methods, namely, PO (Physical Optics) which allows the 3CM to be frequency scalable, polarimetric, and dielectric materials oriented.  ...  In this context, this paper presents a new simplified model, called 3CM (3-Component Model) to reproduce building scattering in an efficient way which strongly improves computation performances.  ...  The authors would also like to particularly thank Paul Thevenon from CNES and Guillaume Carrie from Onera for their participation.  ...
